In a study conducted in Hebei Province, China, liquid chromatography-triple quadrupole-linear ion trap mass spectrometry (LC-TQ-LIT-MS) was used to analyze 90 different antibiotics in 31 water samples, including surface water, groundwater, and waste leachate from three urban landfills. This analysis included hormones, broad-spectrum antimicrobials, macrolides, tetracyclines, β-lactams, sulfonamides, and quinolones. The study’s results indicated that quinolones, β-lactams, and macrolides were the most frequently detected substances in the landfills. It is noteworthy that the concentrations of these antibiotics varied significantly among different cities, reflecting local production and living characteristics. The results of the tests showed that the concentration of amoxicillin was 1171 ng/L in surface water, 811 ng/L in groundwater, and 1926 ng/L of ciprofloxacin in waste leachate. Furthermore, a consistent pattern was observed between the compounds present in the leachate, groundwater, and surface water at the three sites. Risk assessments revealed that the ecological risk was higher for surface water and lower for groundwater. This study is the first to systematically analyze the pollution status of antibiotics and hormones in the water around the landfill in Hebei Province, which not only fills the blank of groundwater-related research in Hebei Province but also provides key data support and theoretical basis for local groundwater hydrological and environmental detection and pollution prevention.</div></div>","PeriodicalId":45329,"journal":{"name":"China Geology","volume":"8 3","pages":"Pages 598-606"},"PeriodicalIF":4.7,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144756704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In arid and semi-arid regions, wind-driven transport of these toxic metals from mining areas represents a primary mechanism for their spatial distribution. To evaluate pollution levels and associated health risks of eight metals, A total of 95 soil samples, corresponding 25 vegetable samples and 3 tailing samples were collected from various land types surrounding a typical Pb-Zn mine in northern China’s semi-arid region. The mean concentrations of As, Cd, Cr, Cu, Hg, Ni, Pb and Zn in soils were 62.8, 0.27, 29.6, 11.5, 0.02, 14.4, 49.9 and 109.5 mg/kg, respectively. Among these, As, Cd, Pb, and Zn emerged as the predominant pollutants, with some samples exceeding national risk screening values. The results of contamination factor (<em>CF</em>), pollution load index (<em>PLI</em>) and geo-accumulation index (<em>I</em>_geo) indicated that heavy metals in most soils exhibited non-polluted level or slight pollution level, though localized severe contamination by As, Cd, Pb, and Zn was observed. Spatial distribution analysis demonstrated similar dispersion patterns for As, Cd, Pb, and Zn, with wind-mediated transport extending up to 2.0 km from contamination sources. Pearson’s correlation analysis and principal component analysis (<em>PCA</em>) suggested that As, Cd, Pb and Zn mainly originated from mining activities, and Cr, Ni, Cu and Hg derived from soil parent materials. All vegetable samples contained metal concentrations below food safety thresholds. Health risk assessment showed hazard quotient (HQ) values for individual metals below 1 across all exposure groups, indicating negligible non-carcinogenic risk. Similarly, carcinogenic risk (CR) values for As, Cd, Cr, and Pb fell within acceptable ranges. While mining activities have induced significant localized contamination, the overall affected area remains limited in arid and semi-arid regions. However, greater attention should be directed toward potential health implications from vegetable consumption in proximity to mining operations within arid and semi-arid regions.</div></div>","PeriodicalId":45329,"journal":{"name":"China Geology","volume":"8 3","pages":"Pages 487-499"},"PeriodicalIF":4.7,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144757051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both zinc deficiency and excess will cause damage to cells, and zinc deficiency in the human body may lead to severe health problems. Zinc deficiency has been identified as a global nutritional issue. Wheat, one of the most significant food crops for humans, is primarily planted in potentially zinc-deficient, calcareous soils in China. It proves to be a major global challenge to increase the zinc concentration in wheat crops to boost crop yields and improve human health. This study investigated the growth process of wheat in calcareous soils with various zinc concentrations using outdoor pot experiments and systematically explored the characteristics and mechanism of zinc transport in the soil-wheat system. The results indicate that the zinc concentrations in various wheat organs decreased in the order of roots, stems, and leaves in the jointing stage and in the order of seeds, roots, and stems in the mature stage. Overall, the zinc enrichment in various wheat organs decreased in the order of seeds, roots, stems, and leaves. In the case of zinc deficiency in soils, wheat roots exhibited elevated zinc availability in the rhizosphere by secreting phytosiderophores. This enhances the zinc uptake capacity of wheat roots. In the case of sufficient zinc supply from soils, chelated zinc formed with citric acid as the chelating ligand occurred stably in soils, contributing to enhanced utilization and uptake rates of zinc, along with elevated transport and enrichment capacities of zinc inside the plants. The results indicate that the zinc concentration in wheat seeds can be somewhat enhanced by regulating the background value of bioavailable zinc concentration in soils. A moderate zinc concentration gradient of 1.0 mg/kg is unfavorable for zinc accumulation in wheat seeds, while a high zinc concentration gradient of 6.0 mg/kg corresponds to the highest degree of zinc enrichment in wheat seeds. This study holds critical scientific significance for enhancing the zinc supply capacity of soils, increasing the zinc concentrations in wheat seeds, and, accordingly, addressing zinc deficiency in the human body. Additionally, this study offers a mechanistic reference and basis for research on the interplay between soils, plants, and human health.</div></div>","PeriodicalId":45329,"journal":{"name":"China Geology","volume":"8 3","pages":"Pages 573-585"},"PeriodicalIF":4.7,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144757056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The differential stress of the shear zone is 20‒40 MPa using quartz paleopiezometry. The dikes within the shear zone yielded zircon U-Pb ages of 165‒163 Ma. However, due to the ambiguous geological relationship between the dikes and shear zone, additional geochronology is warranted. Since the Mesozoic era, based on the exposure of mylonite and dikes, the upper crust has been extensively eroded, exposing the ductile shear zone.
